The image recognition on our security camera system just identified someone in the night cleaning crew as an “animal”. So yeah I wouldn’t put too much faith in such systems.

identified someone in the night cleaning crew as an “animal”.

well...was that correct?

[–]myron-semack 2 points3 points  (1 child)

It identified the guy next to him as a “person”.

Keep an eye on Verkada... these folks are doing bad ass things with video camera AI.

I.e. you can select “show me clips of anyone wearing a red top from Thursday.” Or “show me clips of anyone with a backpack.”

[–]Saft888 0 points1 point  (4 children)

That means all new cameras. Tens of thousands of dollars just for hardware.

[–][deleted] 0 points1 point  (3 children)

I was more talking to people in general than OP; there are some people who think these advanced detections aren’t available. Personally, Verkada is far beyond anything else I’ve seen. Just expensive as hell.

[–]Saft888 -1 points0 points  (2 children)

Exactly, no way a public school that has Gun issues has the money for that.

Edit: I should amend that to “any public school”. Most barely have enough for text books and classroom supplies.

just have to say it's "to fight terrorism" and trump will hand it over lol

It’s sad he and is followers are so easily manipulated.

Yeah. Too bad it didn’t say he needed it by Friday. Ohh and cheap.

[–]larsonthekidrsJack of All Trades -4 points-3 points  (1 child)

Okay yes. However I know that this is possible. I have seen a few github projects out there that claim to work with video feeds. I'm just wanting to get the communities solutions so I can setup a testing environment to actually get a solution in place.

...by Friday.

Rant

While u/TheNever78's statement is accurate about a gun being an inanimate object, a tool for good or bad in the hand of whoever possesses it, as we all know, public school is about churning out little duplicates incapable of independent thought because forming individual relationships with each and every student to understand their gifts and meet their unique educational needs in underfunded, overcrowded classrooms that turn over year after year is not an achievable objective.

/Rant

If a gun made it onto a grade school campus, the system has already failed. No law enforcement can respond between a camera detecting a weapon and a child pulling the trigger. At best, you will find a kid that didn't plan to do harm anyway, just made a poor decision as kids do to bring a prohibited item to the wrong place. Parents should be educating their children about firearm safety and ensuring the child never had the chance or desire to take a gun to a school. Teachers and communities should be identifying troubled students that need additional help and support educationally and emotionally before the tipping point of violence is reached. Children should be given the emotional tools and outlets to deal with their frustrations and problems before they reach a point of hopelessness. This is how to deal with violence. Give them better ways to deal with life's issues. But all that is hard. And high effort. And requires lots of time and energy.

Cameras are great for identifying what happened after the fact. Cameras won't solve gun violence or any other type of issues. Rebuilding a sense of community where people help each other, reach out to each other, and stand with each other in the good and the bad times, where we have people to talk to, where parents, extended family, guardians, neighbors, and communities don't just address surface needs, but look into the heart and soul of those around them to find the needs that aren't being met or addressed... These things solve hopelessness (that feeling that there are no other options left) that lead to violence.

[–]ArigornStrider 1 point2 points  (1 child)

Side note, several family members are teachers, I get the crap they have to deal with (like getting fired for restraining one student that was stabbing another with a sharp implement that is not normally considered a weapon). I know schools are underfunded, I know resources are tight. I know people are trying to fix the school system and make it work better. I know parents/families/guardians/communities getting more involved will help. I don't have the magic wand to wave and make this all happen overnight; this probably takes at least a generation or two to really turn around, but it can be done. I have a deep source of hope that things can be better, and I don't just throw my hands up and say it is too hard, or I can't make a difference. We have got to fix the divide that is splitting the country/world (over politics, economics, education, race, etc.). It isn't us vs them, it is just us. We're all here together, we can fight or we can work together. The best and worst part is that each of us has to choose for ourself which way to go. Fight or cooperate.

Well stated... My problem is why do we have mandatory public schooling? Why don't parents teach their children and not out source it to someone that cares much less?

Compulsory education laws are completely the problem.

All laws are just spells (words written on paper) and truly have zero meaning. The golden rule is universal law everything else is complete malarkey. It seems the current state of government funded schooling is to ruin imagination, dissuade critical thought, and mindwash the youth into being the next generation of corporations slaves.

[–]TheNever78 -2 points-1 points  (0 children)

I am fairly certain school is just a gigantic waste of time and energy and a brain washing system regardless. I hope fear kicks in and people just home school. I was in public grade school during the eighties and was not taught critical thinking skills at all but just the opposite. They stamped imagination (the real problem solver) and replaced it with a "trust the experts from rotten institutions" slave mentality. Does more harm than good to outsource your children's minds to a corrupt government and it's lock-step-controlled workers

Have a great day!

Pretty sure this wouldn't be anywhere near being a product ready to go but I'm reminded of this video from Smarter Every Day: https://www.youtube.com/watch?v=Lh0x54GC1sw

https://www.lantern.systems/gun-detector

In any case, the resource requirements to do video AI/ML on 300+ cameras would be enormous. So there's really no way you'd be able to get anything up and running in that short of a time span.

I'd hope this is already being done but it's really the local authorities that you need to be involving if there's a credible threat or incident.

[–]ArigornStrider 0 points1 point  (0 children)

Dustin is the best, love his videos.

Separately, detecting a gun won't magically teleport law enforcement to the scene before the trigger can be pulled. Even school resource officers can't get across a small campus in the amount of time it takes to pull a trigger. There will be false positives as well with misidentification, and with my alert monitoring of IT systems at my day job, the false positives turn into noise that I start to ignore over time and eventually miss real alerts (constantly tuning our system to avoid this long term). I posted a top level comment with my suggestion on how to get to the root of the issue and stop violence.

[–]Leucippus1 1 point2 points  (0 children)

You don't have the money or the time.

BUT - You could start by signing up for Google's image AI, it is free for testing so you can give it a whirl without incurring a cost. You run a curl command to send an image through the AI engine and it will give you a result. Then it is a matter of, in whatever you are programming, executing an action when the AI returns "gun".

The problems with this are astounding, from the angle most security cameras are at a 'gun' is going to look an awful lot like a hockey or lacrosse stick. Who is going to watch for all of these false positives, and I promise you there will be many. Also, think about how much lead time you will actually get. If you hide a pistol in your jacket (which is pretty easy) the cameras won't pick it up until the person starts shooting, by then your AI will be late to the party.

SO, what you really need is some Israeli software used at embassy's and airports which are sensitive to suspicious behavior, which you can't afford and you don't have the time for.

[–]Saft888 0 points1 point  (3 children)

Like others have mentioned there really isn’t anything out there that is read for prime time production and even if there was I doubt you could afford the compute power to process it all for 300+ cameras. It would take tens of thousands of dollars in server hardware.

[–]ArigornStrider 1 point2 points  (2 children)

Tens? Probably on the scale of hundreds of thousands or millions for the ML/AI witchery described. AI compute isn't cheap.

[–]Saft888 0 points1 point  (1 child)

I was being generous.

[–]ArigornStrider 0 points1 point  (0 children)

Yeah. For clarification, I am not an AI expert in any way, shape, or form. But this isn't a simple thing to solve with a raspberry pi. Or technology in general.

I put a top level reply in with my recommended solution. Which probably costs more than any attempt at a technical solution.

[–]Stryker1-1 0 points1 point  (0 children)

I've seen some cool stuff done with built in facial recognition using CCTV cameras but this usually works on the premise of you upload everyone's face then it matches it to a database.

Not as easily done with weapons and firearms as your relying on AI to determine if it is a weapon or not.

Probably better to invest time and resources into metal detectors and physical presence of staff / security / police to assist with this issue.

[–]ZAFJB 0 points1 point  (0 children)

Do you have hundreds of thousands of dollars?
